I came to this book after reading Sylvia Earle's books on Sea Change and Why the Planet is Blue....no guilt about plugging these at the same time. Eminently readable and full of historical flash back, putting the present era within the longer perspective. Callum Roberts also features in the DVD The End of the Line, and his cheery smiling face contrasts chillingly with and commensurately increases the import of his message. This book is a must read for all interested in marine life, the future of the oceans and the essential food chain within in. Fish are the basic food of a large proportion of the population of the planet; without fish the food crisis will enter nuclear proportions. The impact of factory fishing cannot be overstated - as a diver I'm always shocked when I enter the waters around the UK (Wales,usually) as I always feel 'something is missing'...it's the fish!! And not only the fish but the variety of life underwater....oh, and the startling increase in jellyfish. Can we eat these? And when you've read this, buy his next book, published this year - 'Ocean of Life'. I promise you if you have any capacity for reason you will listen to the science and concur that we need to act now. Informative and inspiring.
